Then how come he is 0-2 vs wrestlers of comparable skill this season? The easiest and most accurate way to predict future behavior or performance is to review past experiences and extrapolate forwards. Nico is 0-2 in close matches this year. If you had to ask me what the most common result would be if he wrestled Tomasello/Dance/Gilman I would tell you it would be Nico losing a close match. The reason I would say that is because that's exactly what has happened thus far. There is absolutely zero evidence from this season to show that Nico is capable of winning a close match vs the 1-3 ranked wrestlers in the weight class. Maybe there was in seasons prior, but this year he's fallen short twice. That leads me to believe he will again. Of course we're talking about 60/40 splits as far as who will win in those situations, not some landslid which might be inferred from my critical language, but it's always more reasonable to assume the outcome in the future will be the same as that which has repeated itself in the past.
I do think that Nico has an approximately a 40% chance to beat Dance, Gilman and Tomasello. The problem for me (and this is as person rooted in logic to a fault) I don't see him doing something he has failed to do twice this year (that is to beat Dance or Nato (and I'm lumping Gilman into this group because he's looked very good this year)) twice consecutively at Nationals. I unfairly and inaccurately exaggerated when I said "near zero" percent chance of doing so earlier, but if you asked me what the most likely result at Nationals is, Nico getting 1/2 or 3/4, I would (and I think anyone who has objectively watched Nico wrestle this year would agree) take Nico to get 3/4 as the most likely result, then 2nd and lastly 1st.
I get that a lot of people feel that Nico has been close to beating NaTo and Dance and that's a correct and perfectly viable assertion which I agree with. He has been close both times, but he lost both times. 125 is just an exceedingly close weight class. All those guys are right there with one another, but Tomasello seems to find a way to win in those close situations against other top guys where Nico has not.
Lastly I'd like to say that I hope I'm wrong in all this, but I personally have a easier time (due to my general outlook on life and past experiences) approaching these sort of scenarios as expecting past results to continue and being pleasantly surprised when they don't versus expecting Nico to win when all the information I've observed tells me that it's likely he won't. So here's me looking forward to being surprised. I want someone to be able to tell me "I told you so" in person at MSG.
